Study Identifies Factors Linked with Better Medication Response for Treatment of Juvenile Arthritis, Erasmus MC Study

Among patients with juvenile idiopathic arthritis (JIA) who initiated treatment with the drug etanercept, one-third achieved an excellent response, and this response was associated with low measures of disability at study entry, younger age at the onset of JIA, and fewer disease-modifying antirheumatic drugs used before initiating etanercept, according to a study appearing in JAMA. The study is being released early online to coincide with its presentation at the American College of Rheumatology/Association of Rheumatology Health Professionals Annual Scientific Meeting.
